REMOTE OPERATION

5.1.

Interfaces

The following sections detail the operation of the instrument via both GPIB and ARC.
Where operation is identical no distinction is made between the two. Where differences
occur these are detailed in the appropriate sections or in some cases separate sections for
GPIB and ARC. It is therefore only necessary to read the general sections and those
sections specific to the interface of interest. At power-on the instrument will be in the local
state with the REMOTE lamp off. In this state all keyboard operations are possible. When
the instrument is addressed to listen and a command is received the remote state will be
entered and the REMOTE lamp will be turned on. In this state the keyboard is locked out
and remote commands only will be processed. The instrument may be returned to the local
state by pressing EDIT which doubles as the LOCAL key; however, the effect of this action
will remain only until the instrument is addressed again or receives another character from
the interface, when the remote state will once again be entered.

5.1.1. Address and Baud Rate Selection

For successful operation each instrument connected to the ARC or GPIB must be assigned
a unique address and, in the case of ARC, all must be set to the same baud rate.
The instruments remote address for operation on both the ARC and GPIB interfaces is set
via the InterFace menu accessed by pressing the I/F button.
With the edit cursor in the REMOTE field, the selected interface can be toggled between
RS232 and GPIB with alternate presses of the DIGIT keys, or by using the rotary control. If
no GPIB interface is fitted an error message will show if GPIB selection is attempted and
the setting will be left at RS232.
The address is selected with the edit cursor in the ADDRESS field, using the DIGIT keys or
rotary control.
Lastly the baud rate is selected with the edit cursor in the BAUD RATE field again using the
DIGIT keys or rotary control.
When operating on the GPIB all device operations are performed through a single primary
address; no secondary addressing is used.
NOTE: GPIB address 31 is not allowed by the IEEE 488 standards and it is not possible to
select it even as an ARC address.
